How can I upload three images as a limit to the database, each image to separate column using PHP? [duplicate]

I have a single input field with the 'multiple' attribute that allows users to upload images. However, I want to restrict the number of images that can be uploaded to three. Additionally, I'd like each uploaded image to be inserted into a separate column in the database, where I have columns named 'firstimg,' 'secondimg,' and 'thirdimg.'

Moreover, I want these uploaded images to be transferred to a folder named 'accountimages'. How can I achieve this functionality in my web application?

<form action="submit_upload.php" method="post" enctype="multipart/form-data">
                <label for="multiple-imgs" id="multiple-imgs-label">
                    <input type="file" class="multiple-imgs" id="multiple-imgs" name="multiple-imgs[]" accept="image/*"
                        multiple hidden>
                    <div id="multiple-imgs-view">
                        <img src="icon.png" id="icon-img">
                    </div>
                </label>
            <div class="submit-btn-container">
                <button type="submit" class="submit-btn" id="submit-btn" name="submit-btn">Submit</button>
            </div>
    </form>

I've been exploring various approaches to implement this feature in my web application, but I haven't been successful so far.

I was expecting that I could find a solution to limit the image uploads to three, insert them into separate database columns ('firstimg,' 'secondimg,' and 'thirdimg'), and also transfer these images to a folder named 'accountimages'.
